About: Paco (pacKAGE oRGANIZER) is a simple, yet powerful tool to aid package management when installing programs from source code. It uses the LD_PRELOAD method to track package installations, and provides various options to keep the installed software organized. It s mainly a command line application but it has also an optional GTKMM interface. Release focus: Minor bugfixes Changes: Libpaco-log has been rewritten in C. This prevents a glibc installation failure when building LFS in chapter 6. The option -x|--expand has been removed. Several bugs have been fixed in paco, gpaco, and rpm2paco. Author: David Rosal

GTRACK Track mouse position and show coordinates in figure title. Once GTRACK is active the mouse position is constantly tracked and printed on the current figure title. A left-click will print the coordinates in the command line and store them. Clicking the mouse right button deactivates GTRACK.

water temperature control system uses the Single Chip Microcomputer to carry on temperature real-time gathering and controling. DS18B20, digitized temperature sensor, provides the temperature signal by "a main line". In -10～+85℃ the scope, DS18B20’s inherent measuring accuracy is 0.5 ℃. The water temperature real-time control system uses the electricity nichrome wire carring on temperature increiseament and operates the electric fan to realize the temperature decrease control. The system has the higher measuring accuracy and the control precision, it also can complete the elevation of temperature and the temperature decrease control.

The Stanford IBE library is a C implementation of the Boneh-Franklin identity-based encryption scheme. (See Boneh and Franklin, "Identity-Based Encryption from the Weil Pairing", CRYPTO 2001.) There are a few modifications and additions. The Boneh-Franklin scheme is used as a Key Encapsulation Mechanism, and off-the-shelf ciphers and HMACs are used for the actual encryption. (See Lynn, "Authenticated Identity-Based Encryption", available on eprint.

TFIND searches for one or more strings (boolean AND) in a text file. TFIND reports all lines where the string(s) were found (or NOT found by option). The search can be limited to a field in a fixed field (i.e. column oriented) list. An extended search mode is available, where only letters and digits are relevant. Other options: case sensitive search, alternative errorlevel with number of hits, header line with file name, LFN, custom prefix

This the second tutorial of the Writing Device Drivers series. There seems to be a lot of interest in the topic, so this article will pick up where the first left off. The main focus of these articles will be to build up little by little the knowledge needed to write device drivers. In this article, we will be building on the same example source code used in part one. In this article, we will expand on that code to include Read functionality, Handle Input/Ouput Controls also known as IOCTLs, and learn a bit more about IRPs.

（1）上电后LCD背光打开，并显示倒计时5秒，然后时钟开始工作。 （2）用模式键（*）切换模式，如显示时间、日期、闹钟1、闹钟2等，并且可以用上、下键控制加1、减1或是闹钟的On、Off。 （3）原程序有16个键，包括0~9数字键，可以直接输入要设置的时间值，但后来将数字键取消了，你仍然可以通过修改程序的部分注释恢复此功能。 （4）闹钟有2路，时间到后闹2分钟，可按任意键取消本次闹钟。闹钟响时有2种音调，是用PIC的PWM实现的。 （5）按任意键可打开背光，1分钟后自动关闭背光。 （6）RA0~RA3为按键扫描输入，应接下拉电阻。
